I understand your premise, but would like you to consider it from the other side as well. Liverpool's ambition at the start of the season was to end up in the top four, when they dropped out of the top six do you think they lowered their ambition for the season?
Your ambition only changes if you are successful, but the season cannot only be judged on halfway stages, it has to be judged as a whole.
i am judging it as a whole, just not on the targets i set pre season.
id imagine after the start of the season they had to end up with 1 (possibly two trophies) Liverpool will consider this season somewhat of a success
and once they realized the players they signed were not as good as they thought (or the squad needed more time together) then they would have altered their ambitions and judge the season accordingly
